.ing piles, walls, foundations and like strucfrom concrete or other plastic mate` tures rials, or fluent solids like sand, and tothe products of said art.

Though our method and its product may be used for a variety of purposes, such, for example, as earth embedded walls, foundations, retaining piles for unstable earth, and any nature, its special object has to do with rthe formation Yand production of piles, especially those made from concrete, and for the sake of illustration ve shall herein describe our invention in thls connection.

The object of our invention is to produce structures such as mentioned, with a series of peripheral'earth locks; and to this end, to provide a simple, economical and effective method for making such structures.

From the accompanying drawings to which reference is hereby made the nature of our invention and the manner in which it is' carried out and the vstructure produced' filling is inserted.

F1g. 2 is a similar section showing the body core or filling in place, land the eect thereof in the completed structure.

Fig. 3 is a detail view showing a modiication with respect to the disposition of A sheathin ciently tlexib e material, as for example, wood or metal or composition which will yield` to the pressure of the filling.,

axis of the This sheathing may be of any shape in crOss' section, circular, oval, or polygonal, according to the nature of the structure. The sheathing is bound at intervals with a series of relatively non-yielding hoo s or bands 2, of metal or other material. hese bands may be disposed as shown 1 and 2, in a plane at right angles to the structure or pile, or they may be helically directed, as m Fig. 3. When first made the sheathing is not distorted byv the bands, and in this condition, Fig. 1, it` is placed in a hole 3 in the ground 4.

Then the` body core, or filling 5 of concrete or other material is placed in the sheathing while it is in the earth. 1

Under the pressure of this filling, which may be due to its weight, or to its weight plus any ramminlwhich ma .be employed,

It will bo understood una if dosima any suitable reinforcement of the concrete f llin may be employed.

Ve'c'laimco 1. The improved method of making structures of the described character which consists -in first sinking a iexible sheathing encircled byperi heral, spaced bands relatively -non-yielda le; andthen-inserting in Said bound sheathing a body fill and causing the vsheathing between lthe ands to bulge peripherally under ressure,

2. A structure of the descri character, comprising a flexible sheathing 5 spaced, peripheral bands relatively non-yieldable, encircling the sheathingnand 'al body filling in the sheathing, Seid fi and sheathing bein bulged between the ands.

n testimony whereof we have signed our names to this s ifcation in the presence of two subscrib witn.
